Iallgatherv_pure

Iallgatherv_pure#

The benchmark for the MPI_Iallgatherv function that measures pure communication time. Every process inputs X bytes and receives the gathered X*np bytes, where np is the number of processes. Unlike Iallgather_pure, this benchmark shows whether MPI produces overhead.
